At Indiana University we deployed Tableau Server 8 in addition to our already used Microsoft BI toolset.
As with any company branding is an important aspect of any delivery. The Tableau Server options are limited however here are some of the options it does allow.
Chang Company NameIn this example the default name when you rollover the Tableau default image is Tableau. I have changed the company name to Cory Retherford for this example.
Change the Company LogoAs you could see from the above image you can also customize the logo as it appears on most web pages.
You can also make all changes and then at the end run the restart command.
Further CustomizationThe following are not supported by TableauIn this example D is the root of where Tableau Server is installed.
D:\Tableau\Tableau_Server\8.0\wgserver\public\D:\Tableau\Tableau_Server\8.0\wgserver\public\images\...and a few others.
